What I have: injection-site erythema · twelve · liraglutide.
I would like to understand the steps well enough to explain them to someone else.
I have access to a refrigerator with a logger and a freezer without one, which may be relevant.
Which parts of this are load-bearing and which parts are habit?
Specifically, the incidence figures are dose-related but the timing is escalation-related, and conflating the two produces most of the bad advice in this area. Adverse events cluster in the one to two weeks following each dose increase, then decay.
Nausea incidence in the pivotal trials runs to roughly 40 to 45 per cent at the higher doses against 15 to 20 per cent on placebo, with vomiting at roughly 15 to 25 per cent against 5 to 8 per cent. Discontinuation specifically attributable to gastrointestinal adverse events was in the range of 4 to 7 per cent. Those are the numbers to hold in mind when someone describes their experience as unusual.
| Feature | Local reaction | Sterile abscess | Cellulitis |
|---|---|---|---|
| Onset | Hours to 2 days | Days | 1–4 days, progressive |
| Warmth | Absent or minimal | Mild | Marked |
| Expansion | Static or shrinking | Slow | Expanding |
| Texture | Firm, flat or raised | Fluctuant | Diffuse, indurated |
| Systemic features | None | None | Fever, malaise possible |
| Action | Observe, rotate site | Clinical review | Same-day clinical review |
The relevant detail is that the telogen effluvium timing signature is the diagnostic feature: hair enters the shedding phase two to four months after the insult, so shedding that starts at month three of rapid loss and peaks around month four to five is the expected pattern. Shedding that starts in week two is not telogen effluvium and warrants a different question. In either case the follicle is not destroyed and regrowth is the rule.
The pooled gastrointestinal adverse-event rates across the STEP programme and the SURMOUNT programme are reported in the primary publications and in the FDA and EMA assessment reports, and the assessment reports are more useful because they give the placebo-arm rates alongside the active-arm rates in the same table.
Worth being explicit: nothing here is medical advice, and research-use-only compounds are not approved for human use.
If the timing does not fit the escalation, look for another explanation before settling on the drug.
